You have probably heard us mention the new Turbocharger Mazda 6 in the recent weeks and months and have probably been wondering; “what’s going on?” Well, today we’d like to share a little bit about what’s been going on at CorkSport HQ with our very own 2018 Mazda 6.

Right off the bat, I can say we have a handful of exciting performance products in the works and will be sharing info on them as we make progress. Today we want to talk about the intercooler piping, specifically the cold side piping and the parts of the system. This is the piping that connects the outlet of the intercooler and the throttle body. It is commonly referenced as the “cold side piping” because the charge (boosted) air has passed through the intercooler and is therefore cooler.

The OE cold side piping consists of three main components. Starting on the right side of the image; we have the hard piping that connects to the intercooler and a soft rubber hose. Next is the soft rubber hose itself, which we will talk more about later. Lastly is the throttle body connection, which is the oddest part of this system. You can see why in the next image.

The above-mentioned intercooler hard pipe and the rubber hose are pretty common parts on modern turbocharged vehicles, but the throttle body connection is unusual from our experience. The throttle body connection appears to be designed for a quick connection (and not so quick disconnection) during the vehicle assembly process. Unfortunately, this leaves a very odd connection flange on the throttle body itself. Lastly are the fins inside the connection part; other than straightening the airflow entering the throttle body we don’t see many purposes these. We will be testing the effects and need for these in the near future.

Now let’s get to what we really wanted to talk about; BIG Silicone Performance Parts.

Mazda designed the Turbocharged 2.5L SkyActiv-G to function at a specified boost pressure and no more. However, we fully intend to change this set boost pressure for increased smiles per gallon. With increased boost pressure comes more force and strain on the OE rubber hose. Eventually, the OE rubber hose becomes too flimsy for the increased boost pressure and may expand or fail completely via a rupture.

So how do we develop a performance part to replace a rubber hose? Well, there is one obvious improvement and another not-so-obvious change that can be made. First, we use silicone as the prominent material for its excellent heat resistance and durability. Next, the silicone is reinforced with five layers of fabric braiding to withstand the increased boost pressures. Compare this to the OE single layer of reinforcement and you can see why this would make a big difference.

Now for the less obvious performance improvement; the CorkSport 3D Printed prototype is larger in diameter than the OE rubber hose. Leaning on our experience with past intercooler piping development, we have found that increasing the charge air volume directly in front of the throttle body increases throttle response and helps spool the turbo faster, reducing turbo lag.

Currently, we are still in the development phase but will be testing soon. Stay tuned for future updates on the CorkSport Performance Boost Tube and other exciting products for your 2018 Mazda 6.

Breathe Some More Life into Your CX-3

Bought a new CX-3 and wish it was a little more exciting? CorkSport can help with our lowering springs, short ram intake, and now we are proud to introduce the CorkSport Axle Back Exhaust for 2016+ Mazda CX-3 AWD.

The CorkSport axle back really gives the little bit extra that the CX-3 needs to be a fun & practical little car. By increasing the piping diameter to 60.5mm and using dual high flowing resonators, the CS CX-3 axle back provides much better sound than OE without being “buzzy” or annoying like so many exhaust option on the market. It’s louder than OE but not drastically so, plus, it avoids any drone while cruising down the highway. Check out the video below to hear how the CorkSport axleback sounds.

To go with the sound the CorkSport CX3 axle back looks great. Made from fully polished T-304 stainless steel, it will add some style to the rear of your CX-3 right away and stay looking good for years to come. The tips have been enlarged to 90mm, slant cut, and lengthened slightly to really fill out the bumper cutouts. For a final detail, a stainless CorkSport nameplate is attached to each tip and just barely peeks out from under the bumper.

As usual, you get the same OE fitment and reliability that you can always expect from us at CorkSport. As a result, this really is a no drawback product that adds a little bit more excitement to the CX-3. If you want to add some extra sound and style to your CX3 look no further than the CorkSport Axle Back Exhaust.

Well guys, I am back with a part 3. I apologize in advance for the delayed release of the 3rd chapter, but the Mazda was out of commission for a bit getting some stuff reworked! That being said, we can now pick up where we left off in part 2!

As I started to settle into my new stake at CorkSport, I started adding on lots of new goodies. At the beginning of the new year of 2017, I got to throw on our prototype Stage II RMM and get rid of my old one for some testing and feedback. Not only did the vibes decrease substantially, it also held the powertrain better and was helping my wheel hop significantly. So while I was at it, I threw on a Lower Tie Bar to help even further, knowing I had plans in the very near future to make over 400 Whp. It was now Feb. of 2017 and I knew I was wanting to reach my new power goal by Summer. So, I talked to my tuner, Erik with Drama Tune, and scheduled to fly him up here in March to dyno tune the car. I had every single piece needed to complete the 400+ Whp puzzle.

The last missing piece was fuel. At this point in time, I had two options, Port Injection or Methanol Injection. Given, that I only needed a little more fueling head room freed up I went with methanol for ease, and price. For those that are curious, I purchased the Snow Performance Stage 3 Kit. I started installing the kit at the beginning of March 2017. Since I was going to be putting bungs into the FMIC piping, I got the kit powder coated as well. I installed one small nozzle right off the cold-pipe of the intercooler, and another large nozzle right before the throttle body. I left a couple inches to help the alcohol atomize. The total amount I was spraying between the two nozzles was approximately 1000 CC’s of 100% Meth as we were using it for Fuel.

So, with the car ready my Tuner flew up and we got my car on the Dyno! Keep in mind my car is a stock bottom end, so I knew I was going to be playing with fire a bit. The general rule of thumb here: If you are on a stock bottom end and want to push the car in this fashion, always have a backup plan ready in case the engine gives out. By the end of the session, I had 3 maps from Erik: Pump Gas: 340 Whp

E85 Blend (3 Gallons): 390 Whp

Methanol Injection: 430 Whp. (e85 still in the tank for added knock resistance and cooling)

The torque was kept down as much as possible at 380 Ft-lbs @ 4700 RPM. So, the stock rods definitely were not in danger. Ultimately if the block were to give out in this situation, it would more than likely be the piston rings. The stock Piston Rings do not like high heat or harsh temp changes. So, the best thing you can do pushing 400+ hp on the stock bottom end is to allow time between pulls for everything to re-stabilize. This will ultimately increase the time you have before it ‘Splodes. Because, if we are being honest with ourselves, at that power level, its always a matter of when, not if with the stock block.

So, this is how my MS3 has been for the last year or so power wise. Built block will be in the future soon. But on this next part, I’ll dive into some cosmetics details that I’m sure a lot of people wants to know.

For those that don’t know exactly what an OCC is for, here is a quick rundown.

During normal operation of an internal combustion engine, there’s a compressed air and fuel mixture inside the combustion chamber that is ignited and as a result, forces the piston down. A small amount of that ignited mixture leaks past the piston rings and ends up in the crankcase. This leakage is often referred to as “blow-by” (leakage past the piston rings), and is the reason every car has a PCV System in place (Positive crankcase ventilation)

Some of the oil, mist and other products settle along the engine intake and over time form a “gunk.” With newer cars being direct injected nowadays, this becomes an even larger problem when fuel is not passing over the intake valves and keeping them clean. The OCC collects the PCV vapors and utilizes a baffle to trap the oil, fuel, and water particulates that are suspended in the air.

These liquids will need to be drained periodically (we say with each oil change) of all the ‘junk’. NOTE: Monitoring how fast the can fills up, mirrors as a method of gauging engine heath. More blow by = Quicker Filling OCC.

Carl Jacobsen recently reviewed our Mazda3 OCC in an interview, and we’re releasing it here so you can hear it from a satisfied customer, and not just our opinion.

From the start, we have wanted to give our customers the highest quality experience when purchasing the OCC for their Mazda3. The importance of knowing and seeing you have every piece you need to get started is the key to a successful installation.

“ The unboxing is the best part. You know everything is there, even the step by step instructions. (I tried not to use them, but I ended up doing so because they’re spot on all the way down to the bolt sizes).”

All of our installation instructions come with step by step tips and tricks to make things easy along the way. However, if you ever hit a hiccup, just know we’re only a call away!!

“ Installation was a breeze, instructions were spot on, some parts – like the mount are hard to install without help, but nothing you couldn’t do on your own… ”

As far as the CorkSport Mazda3 Oil Catch Can goes, knowing that all the crankcase vapors are getting filtered out, allows for you to have that peace of mind that your engine is cleaner. Without filling up the space in your engine bay!

“The OCC is hidden, it doesn’t take up space in the engine bay. You’d never know it was there unless you follow the lines. Also, the ease of access to drain it was a highlight! There was more than enough tubing to route the drain plug to the easiest spot, so you can drain it when changing your oil.”

Oh man, where to start.

Day one, was a 6-hour drive from Utah to Boise Idaho. I was supposed to head out with a couple of other Utah guys, but they were not able to make it. I was on my own for 6 and the only thing going through my head was, “I’m on my own, driving to a town I know no one in, I have zero friends and that I’ll probably be the only Mazda 3 there”. I made it my goal to make friends wherever it is I go or else this was going to be a alone and this trip would have been a waste. As I get into town I settled into my Airbnb and decided to hit the town. I only saw one speed that night but I was anxious for the next day to go to the events start.

Day two, I went to this pancake house to grab some grub and I was shaking out of excitement. I head over to Keith’s house and see four speeds outside. I immediately knew I was in the right place. I walk up to Keith and welcomes me with open arms and announces I am the only Utah guy to show up this year. I start talking to everyone and get to meet everyone who shows up and I’m having a blast every one welcoming me to Idaho and the first takeover for me.

Keith announces we will be going to horseshoe bend. A canyon drive day one, one I will never forget. It was a beautiful sight the entire time. Brett hanging out of Corey’s MX-5 MSM taking beautiful shots of everyone’s cars and even a drone in the sky.

Later that day we head off to start our first competition of the weekend, go-karting. Name of the game fastest lap time wins a prize. I can’t remember who it was that won. Then that night was BBQ night and drinks all around. That’s when I got to meet everyone else who had shown up, share a couple of beers and enjoy the CorkSport koozies that were handed out.

Day three, I woke up in my car…well because of the night before.

Saturday was a slow and relaxed day of just hanging out in the garage hiding from the rain. While we hanging out in the garage some of the Oregon guys decided to adopt me and I can join them since I was the only Utahan. I also got to talk to Dale and pick his brain about tuning and learned a bunch about speed that I had no knowledge of as well. Later that night we head off to the raceway and I’m excited to see everyone run and see lap times everyone was laying down. There were a bunch of cool cars and Barett laying down some fast times on street tires.

Day four, the last day.

Everyone meets up to say their goodbyes, have a beer or two, share some last tales. The few people that have left a great memory for me where Keith, Jordan, Anthony, Aaron, Dale, Brett, Corey, and how could I ever forget Brian. As I head back to Utah with everyone on my mind and how my entire weekend went I wanted to turn around and just stay. I had made new Mazda Friends and Family.

Those four days were ones I could never forget. The feeling of being accepted into a group of people I didn’t know and didn’t necessarily fit in with was one that cannot be explained. It can only be experienced. When I came back to Utah, I couldn’t stop thinking about my vacation in Idaho. How it ended so soon. How it felt like I started a new life for just 4 days. I want next year to come sooner so that I may meet the friends and family I now have in Idaho, Washington, and in Oregon. Thank all of you again for the wonderful experience.
